Christina AguileraParis Hilton publicly announced Christina Aguilera’s pregnancy at LAX nightclub in Las Vegas on Saturday night.

The rumoured mum-to-be was hosting a pre-VMAs party at the new club in the Luxor Hotel when the socialite grabbed the DJ’s microphone to make the announcement.

According to club goers, Paris said: “I want everyone to say congratulations to the most beautiful pregnant woman in the world, Christina Aguilera. You’re gorgeous!”

Christina and husband Jordan Bratman, who have yet to confirm the pregnancy, are said to have looked initially shocked and Christina dropped her head onto Jordan’s shoulder. The couple quickly recovered though as the celebrity-studded crown applauded.

Pregnancy rumours about Christina have been circulating since the couple were spotted at the Maternal Fetal Medicine Association in New York in June. The baby is said to be due at the end of the year.
